Generating ping sounds

[ScaleRobotics]

There's the old Roman Black method. Sounds are rather hissy, but you can embed it into a pic chip. A ricochet sound mightbe well suited for it, since it might over ride the hiss.

Here's some code with number example. And a wave file you can play for getting an idea of the "quality". Not great, but you can easily tell what numbers they are.

and Darrel's better example:

(In fact, his example has a sort of laser gun sound in it.)

Thanks for the suggestion, I already tested the Roman Black method and found that the sound was just too hissy. It is pretty cool though.

I was hoping that there would be some kind of simple sound circuit I could make from other components. I have seen sine wave generators with 555 timer chips that make wailing sounds. Maybe there is something like this that they use to make 'ding' kind of sounds?

Have a look at this one

Thanks Ioannis, the SOMO-14D looks awesome. I have ordered one and will let you know how it goes.

Ok, I managed to get the SOMO-14D working correctly. It does exactly what it says it should, and plays sounds quite loudly through the speaker connection. It does take a while getting the right SD card for it, but once you have that it's great.

Thanks again for the help!

Great you got it working and your feedback.
